How to Calculate Fahrenheit to Kelvin

What is Fahrenheit to Kelvin?

Kelvin is the SI unit of thermodynamic temperature, used in science and engineering. Converting Fahrenheit to Kelvin requires first converting to Celsius, then adding 273.15. Kelvin has no negative values — 0K is absolute zero, the theoretical minimum temperature.

Formula

Step 1: °C = (°F − 32) × 5/9

C: (°F − 32) × 5/9 — (°F − 32) × 5/9
F: F value — Variable used in the calculation

Step-by-Step Guide

1Step 1: °C = (°F − 32) × 5/9
2Step 2: K = °C + 273.15
3Combined: K = (°F − 32) × 5/9 + 273.15
4Or: K = (°F + 459.67) × 5/9

Worked Examples

Input

32°F (freezing)

Result

273.15 K

0°C + 273.15 = 273.15K

Input

212°F (boiling)

Result

373.15 K

100°C + 273.15 = 373.15K
